The Sun Hydraulics DNDYTXV228 (DNDYTXV228) is a solenoid-operated 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate pathways. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure, making it versatile for various applications. In its de-energized state, it connects the P and T ports to the first circuit and switches to the second circuit when energized. The valve's solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. It features a wet armature design where the working fluid surrounds the armature, which can be a consideration concerning heat dissipation during prolonged coil energization. Various manual override options are available, although they are not compatible with weatherized coils. The valve exhibits high efficiency due to its unique magnetic design, providing significant spool actuating force per watt used and ensuring reliable shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K for enhanced environmental resistance. The cartridge incorporates Sun's floating style construction to minimize binding risks due to installation torque or machining variations in cavity or cartridge dimensions. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this model is well-suited for applications requiring quick switching frequencies up to 15,000 cycles per hour. The valve also supports various coil termination and voltage configurations with optional surge protection features.

This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
